Product Overview

A three piece ball valve with socket weld ends is designed for reliable shut-off and easy maintenance in demanding industrial systems. Its split-body construction allows the centre section to be removed for cleaning or seal replacement without cutting the pipe, while the socket weld connection provides a strong, leak-resistant joint for high-pressure and high-temperature service.

Product Features

Three-piece body design allows the centre section to be removed for in-line maintenance without cutting pipework
Socket weld ends provide a permanent, leak-resistant connection for high-pressure and high-temperature applications
Full port (full bore) design ensures minimal pressure drop and unrestricted flow
304 or 316 stainless steel construction offers excellent corrosion resistance and long service life
PTFE or R-PTFE seats support reliable sealing across a wide temperature range
Suitable for 1000 WOG service, depending on size and configuration
Quarter-turn operation enables fast, positive shut-off and easy automation
